Questions & Answers

Question:

Which way up does this go? Writing inside or out?

Answer:

  • Pre-printed marking lines face outwards

Question:

Is this product water proof/ resistant in any way? Also the writing i am assuming is facing out not inside the house

Answer:

Its water resistant to a degree. And is designed for external use eg. under tiles or cladding 

Question:

Has this product got any writing on? Or is it just plain black?

Answer:

The product has 'Powerlon' printed on it, along with the overlap lines. If you wanted a completely plain black option the best to go for would be the one linked below.

Question:

are there any chemicals in this product?

Answer:

This is a breather membrane so would be like a sythetic fibre material, there is more technical data you can find on the suppliers site below.

Question:

Can this be sealed with tape? If so which tape do I use?

Answer:

Yes, please see tapes on link below. The acrylic ones are for sealing laps between the felt, the bitumen one for when you are mechanically fixing onto a rafter etc to seal around the fixing.
